It's no secret that children can play awful tricks on one another, but you don't usually expect teachers and parents to be in on the prank. But that's exactly what happened during a class canoe trip in Manitoba, Canada, when a parent chaperone tricked two different students into eating moose poop. Karen Eyolfson says her 13-year-old son and a girl from his class were both talked into eating what the parent told them were chocolate-covered almonds that he had in a sandwich baggie. It was actually moose droppings. Nasty.

What's even crazier is that the school principal, a resource officer, and a teacher were all there and let it happen—twice! The boy, who was tricked first, popped one into his mouth, and as soon as he had, the whole group of students and faculty started laughing at him. Someone even helpfully yelled, "You just ate moose shit." Nice. That certainly sounds like something you'd expect from a bunch of 13-year-olds, but not the school principal? Later, the girl, who hadn't seen what happened to the boy, fell for the very same trick and the moose shit got caught in her braces. Oh noooo. She is described simply as having been "humiliated," which sounds like the understatement of the year. For their involvement in this disgusting incident, the three staff members have apparently been disciplined, and one hopes that involves being forced to eat a bunch of "chocolate-covered almonds" while being laughed at by the entire school.
